When I first moved into an Iskcon temple I had already read Prabhupada’s Bhagavad Gita As It Is twice, as well as a few other of Prabhupada’s books. So when I first moved into the ashram and I started reading Radhanath Swami’s The Journey Home almost right away (like most new bhaktas these days it seems) I noticed that Radhanath Swami was praising various bogus gurus and yogis. I found this to be somewhat perplexing as Srila Prabhupada strongly criticized these types of people all throughout his books. I don’t remember asking anybody about this apparent contradiction between what Radhanath Swami was saying about these people and what Prabhupada says about these types of people, however I somehow or other came to the standard Iskcon approved understanding that The Journey Home is a preaching/introductory book and that Radhanath Swami’s intention when praising these pseudo-spiritualists is just to attract people to Krishna without upsetting them with strong criticism.
Harinama diksa guru is someone who gives you initiation, who recites mantra from their heart into yours. Unfortunately, Radhanath baba was not given maha mantra by Prabhupada. He himself explains how he was initiated in his own book called Journey Home, let’s check it out.
